The domain presents recording and audio production services. Enquiries use the listed contact channels; a call or browsing does not confirm a booking. Each job requires a quotation accepted in writing, identifying the provider, scope, price and schedule. Contractual documentation includes the applicable tax and registration details.
2. Purpose of the information
These pages explain services, preparation and proposed terms so you can assess an audio project. Starting rates do not replace a quotation tailored to duration, material and deliverables. The website has no automatic purchase or integrated payment facility. Enquiry hours are Monday to Friday, 10:00–19:00 Madrid time. Read the terms to understand how a session is confirmed and how each item is described before a contract is made.
3. Content and images
Editorial content supports technical and organisational decisions. It does not present unverified testimonials, awards or clients. Images accompany the editorial content. Service details and access requirements are confirmed directly before booking. Mentioned trademarks belong to their owners and do not imply collaboration. Do not copy third-party material supplied during a project without checking permission. Rights in delivered files are governed by the job terms without affecting pre-existing third-party rights.
4. Links and operation
External links lead to independent sources or services. Their later changes are outside this website’s control. Presentation resources are local, with no loaded analytics, advertising or external fonts. The planned FormSubmit integration is described in the privacy policy and awaits activation. Report broken links, access barriers or information requiring correction through the contact channel, identifying the page and describing the issue sufficiently.
5. Applicable framework
The website is interpreted within applicable Spanish and European rules on online services, consumers and personal data. No clause removes mandatory rights. Consumer disputes must respect protective jurisdiction rules; there is no blanket waiver of a consumer’s lawful forum. In B2B relationships, any specific jurisdiction needs a valid contractual agreement. Read the terms, privacy policy and disclaimer before accepting a project.
